### How fast is Planck time?

Planck length and Planck time Planck time is the time it
would take a photon moving at the speed of light in a vacuum to
cross a distance equal to the Planck length. The Planck length is
1.616252 × 10−35 meters, and the Planck time is 5.39121 × 10−44
seconds. Links are provided to the relevant Wikipedia articles.

###### Asked in Units of Measure

### What is smaller than a nanosecond?

An attosecond is one quintillionth (10 to the power of minus 18)
of a second.
As of 2006, the smallest unit of time that was directly measured
was on the order of 1 attosecond (10−18 s), or about 1026 Planck
times.
In physics, the Planck time, (tP), is the unit of time in the
system of natural units known as Planck units. It is the time
required for light to travel, in a vacuum, a distance of 1 Planck
length. The unit is named after Max Planck, who was the first to
propose it.

###### Asked in Time

### What is the smallest unit of measurement in time?

They just divide up seconds, into milli- micro- nano- etc. It's
possible that the shortest interval of time is 10 to the -43 power
seconds ... if time is discreet. Further details: The
smallest measurable and meaningful unit of time is Planck time. In
physics, this is equal to the time it takes for light to travel, in
a vacuum, a distance of 1 Planck length. However, since most of us
cannot relate to physics, the shortest unit of time is the
Yoctosecond, which is one septillionth (short scale) of a
second.

### The smallest unit to measure length is?

The smallest unit is the Planck Length. Theoretically, it is not
that there can be nothing smaller, but for various reasons that
have nothing to do with the limits of technology there is nothing
that can be known about anything that happens to be smaller. For
scale, the number of Planck Lengths in the diameter of a proton is
10 to the twentieth power.

###### Asked in Quantum Mechanics

### Is there such a thing as quantum time?

In physics, a quantum is the minimum unit of any physical entity
involved in an interaction. Since there is no minimum unit of time
that is currently known then, no, there is no quantum time.
Aside: If one thinks of the term "quantum" more colloquially
then you might say that it is a unit that is synonymous with very
tiny therefore you could call a short amount of time a quanta of
time. Example: In physics, the Planck time, (tP), is the unit of
time in the system of natural units known as Planck units. It is
the time required for light to travel, in a vacuum, a distance of 1
Planck length. Planck time is about 5.4*10^(- 44) seconds. The unit
is named after Max Planck, who was the first to propose it.
